Abstract (en)
[origin: EP2690300A1] An outer clutch plate (62) arranged to face an inner clutch plate (61) so as to be relatively rotatable and relatively movable includes a contact surface (sliding surface) (62b) being able to contact the inner clutch plate (61) via lubricant and a minute groove (62c) open at the sliding surface (62b) and formed of a plurality of groove portions (620c) having a predetermined groove pitch. A ratio of a contact area of the sliding surface (62b) to an area obtained by adding an opening area of the minute groove (62c) to the contact area of the sliding surface (62b) is 90% to 96% in an initial state.
